* svga: add VS code to set attribute W component to 1Brian Paul2014-04-175-46/+100
| | | | | | | | | | | | | | | There's a few 3-component vertex attribute formats that have no equivalent SVGA3D_DECLTYPE_x format. Previously, we had to use the swtnl code to handle them. This patch lets us use hwtnl for more vertex attribute types by fetching 3-component attributes as 4-component attributes and explicitly setting the W component to 1. This lets us handle PIPE_FORMAT_R16G16B16_SNORM/UNORM and PIPE_FORMAT_R8G8B8_UNORM vertex attribs without using the swtnl path. Fixes piglit normal3b3s GL_SHORT test.

* svga: implement support for signed byte vertex attributesBrian Paul2014-04-176-14/+151
| | | | | | | | | | | | | | There's no SVGA3D_DECLTYPE that directly corresponds to PIPE_FORMAT_R8G8B8_SNORM. Previously, we used the swtnl fallback path to handle this but that's slow and causes invariance issues. Now we fetch the attribute as SVGA3D_DECLTYPE_UBYTE4N and insert some extra VS instructions to remap the attributes from the range [0,1] to the range[-1,1]. Fixes Sauerbraten sw fallback.

| | | | | | | | | | | | | | | | | | | | | | | Our hardware has an "accumulator" register, which can be used to store intermediate results across multiple instructions. Many instructions can implicitly write a value to the accumulator in addition to their normal destination register. This is enabled by the "AccWrEn" flag. This patch introduces a new flag, inst->writes_accumulator, which allows us to express the AccWrEn notion in the IR. It also creates a n ALU2_ACC macro to easily define emitters for instructions that implicitly write the accumulator. Previously, we only supported implicit accumulator writes from the ADDC, SUBB, and MACH instructions. We always enabled them on those instructions, and left them disabled for other instructions. To take advantage of the MAC (multiply-accumulate) instruction, we need to be able to set AccWrEn on other types of instructions.

| | | | | | | | | | | | | | | | | For graphics, the LLVM compiler backend currently has many shortcomings compared to the non-LLVM one. E.g. it can't handle geometry shaders yet, but that's just the tip of the iceberg. So building Mesa with --enable-r600-llvm-compiler is currently not recommended for anyone who doesn't want to work on fixing those issues. However, for protection of users who end up enabling it anyway for some reason, let's disable the LLVM backend at runtime by default. It can be enabled with the environment variable R600_DEBUG=llvm.
